Specification of Letters Patent.

Patented July 10, 1906.

Application filed April 4, 1906. Serial No. 809,778.

To all whom it may concern;

Be it known that-I, WILLIAM F. MURPHY, a citizen of the United States, and a resident of Branch, in the county of Monmouth and tate of New Jersey, have invented new and use Improvements in Mechanical- Movements, of which the following is a full, clear, and exact description. I

This invention is an improvement in me chanical movements, having among other objects to produce a mechanical movement by which rotary motion may be multiplied or reduced with a minimum amount of friction developed in the intervening gearing by which this object is accomplished. A

To this end my invention consists in the combination of a driving-shaft connected to a driven shaft through a driving-disk with intersecting guide-grooves in its face traversed by guide-blocks, a crosshead connecting the b ocks and a crank-shaft on the driven shaft at one end and to a counter-shaft geared to the driven shaft lay suitable cranks and a link at its opposite en movement will be found desirable in boats, locomotives, and other relations where steadiness, smoothness of operation, and a well-balanced movement is desired.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts" in all the fig-.

ures.

Figure 1 is an end elevation, partly broken away, of my improved movement. Fig. 2 is a view similar to Fig. 1 after the drivingdisk has made a uarter-turn, and Fig. 3 is a side elevation of ig. 2.

The numeral 1 indicates a base to which is bolted or otherwise secured standards 2, 3, and-4. The standard 2 is made up of two arms 5, in the up er ends of which is journaled 'a driving-s aft 6, having a crank 7 fixed at one end and to its opposite end a disk 8, to which is secured a driving-disk 9, with two diametrical slots or guideways 10in its face at right angles, to each other. In each guideway 10 is slidabl'y mounted a guide? block 11, with flanged bearing edges 12, said guide-blocks being pivotally connected at theircenter by pins 13 to the horizontal arms ofa cross-head 14.

The standard 3is made u of arms 15 of un-' equal length, the longest 0 which is adjacent to the driving-disk 9 and passes upwardly I consider that I into two branches,-in which is journaled a counter-shaft 17.

The standard 4 is placed a slight distance from the standard 3 and is provided with arms 18, similar to the short arm of this standard, in which is journaled a shaft 19, connected to a short shaft in alinement therewith, journaled in the arms 15'by crank-arms 21 between the standards.

Fixed to the ends of the shaft 17 are respectively cranks 22 and 23, the crank 23 being ivotedv to a vertical arm of the crosshea 14 and the crank 22 pivoted to alink 24, j ournale'd at its lower end on a crank-pin connecting the arms :21. The end of the shaft 20 is extended beyond the standard 3 and has fixed thereto a crank 25, pivoted to a lower vertical arm of the cross-head 14. The crank 25 carries a counterbalancing-weight 26 to balance the cross-head and its attached mechanism.

In the operation of the movement as the shaft 6 is rotated the guide-blocks 11 are reciprocated in the guide-slots 10 of the disk 9, alternately crossing each others path and making a complete u ward and return movement with each revol fition of the disk. With each reciprocation of the guide-blocks 11 the crank-arms 23 and 25, through the crosshead 14, are turned over a complete revolution, thereby drivin the shafts 17, 19, and 20 at. twice the spec of the disk 9 and its attached shaft 6.-

It is evident that various changesmay be made in the details of construction without departing from the spirit of my invention or sacr cing any of the advantages thereof, and

am entitled to such modifications as fall within the scope of the invention as claimed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1., The combination of a driving-shaft, a radially-slotted driving-disk connected thereto,a driven shaft journaled at one end of the driving-shaft, a counter-shaft j ournaledover the driven shaft, crank-arms at each end of the counter-shaft, crank-arms on the driven shaft, a link connecting a crank-arm on the counter-shaft with a crank-arm on the driven shaft, and a cross-head pivotally attached to guide-blocks in the slots of the disk and connecting crank-arms on the driving and counter shafts.
